Strange behavior in somewhat complex layout

Strange behavior in somewhat complex layout

[Andres Conrado Montoya]

[-- Attachment #1.1: Type: text/plain, Size: 3615 bytes --]

Hello list, I'm trying to make something using bits and examples found here
and elsewhere, but I'm hitting a wall. I know there's a flawed logic in my
approach, but I can't figure it out. Any help is appreciated.

Expected behavior of the following MWE:
When starting a new chapter, check if the page is even (left page), if so,
fill it with color, and start the chapter in the next odd page (right
page), removing the header but leaving the footer in that start-chapter
page; and if this is a start-chapter page, use a specific graphic overlay
for the page, but if if not (if its a regular page), use another graphic.

Result:
The header still appears in the start-chapter page, if it comes after the
color filled page. But, if the start-chapter page comes after a regular
(even) page, everything works as expected (no color-filled page, no header
in the start-chapter page).

MWE:

Strange behavior in somewhat complex layout (again)

Hi List, it seems my message went unnoticed, if you can help me out, please
do. I'm an struggling with this layout.

I'm trying to make something using bits and examples found here and
elsewhere, but I'm hitting a wall. I know there's a flawed logic in my
approach, but I can't figure it out. Any help is appreciated.

Expected behavior of the following MWE:

fill it with color, and start the chapter in the next odd page (right
page), removing the header but leaving the footer in that start-chapter
page; and if this is a start-chapter page, use a specific graphic overlay
for the page, but if if not (if its a regular page), use another graphic.

Result:
The header still appears in the start-chapter page, if it comes after the
color filled page. But, if the start-chapter page comes after a regular
(even) page, everything works as expected (no color-filled page, no header
in the start-chapter page).

Apply the above setup with

beforesection=\directsetup{chapter:before},

Wolfgang... Thank you, man. Thank you so very much. This works perfectly.

As I understand it from your correction, my mistake was that I was not
doing the page break before everything else, as I should, because in any
case there will always be a page break in my layout. Then, let the rest of
the algorithm decide if there will be a left or right page, headers and
footers, etc. Am I correct?

Thank you again for your work.

Yes, it's important to do the page check before the section is inserted.

When you use the before key you perform the check after \startchapter 
finished the previous page and removed the header line, when you insert 
now the colored page the header setting is used for this page and one 
the following page with the section title you get the unwanted header text.
